Your brain's basically running through worst-case scenarios when there's genuine uncertainty in your environment. The restructuring and layoffs you're actually witnessing are real threats, so your mind is rehearsing how you'd handle the worst outcome. It's not prophecy - it's just your subconscious doing what it does when there's a real danger signal in your life.
The thing people sometimes miss though is that these dreams can actually make anxiety worse if you start reading too much into them. Like, some folks get stuck in this loop where they have the dream, feel terrified, and then spend the next day hypervigilant at work, looking for "signs" that they're actually about to get fired. That can make everything feel more ominous than it is. The restructuring sucks and it's legitimate to feel worried, but the dream itself isn't telling you anything your waking brain doesn't already know.
What might actually help more than interpreting the dream is just acknowledging that you're in a genuinely uncertain situation right now. If your job actually feels stable, that's worth holding onto. But if there's anything concrete you could do - like updating your resume, networking a bit, or just making sure you have a few months of savings set aside - that tends to settle the anxiety more than dream analysis does. Your brain will probably stop running this scenario once it feels like you've got some kind of plan in place.
